Subject: [alt-beam] Re: PBS special- Poppers
Does anyone know the topology of the newer BeamAnt? I have know how to
make it reverse and attach the Bicore. Is that it?
Also, are the reversers operated solely by the touch sensors, and the
bicore by the photo diodes, or is there something else.
Anyone know what type of SE (PM1 I hear?) and ideal cap & solar panel sizes.
I have a 9 volt 60 mA pannel attached to a pair of MAXON planetary gear
motors. I'm thinking this may be the platform I use, but it's large
(6x6x6 inches with top being the solar panel and a tripod layout with a
scratch built caster wheel in front.
An image of the frame is on my page (Megavore).
I'd love to see those Deluxe Photopoppers. Hehe! (:
